Less spreadsheet cleanup.
More time for your business.

We experiment with focused tools for small teams: CSV cleanup, simple reporting, and custom workflow prototypes. Try the real browser-only CSV cleaner below. There are no subscriptions, account signups, or server file uploads.

COMMON WORKFLOWS

Small problems deserve focused tools.

CSV cleanup

Remove rows whose entire contents are identical, then choose a numeric column to total. Always review actual transactions before accounting use.

Routine reporting

Explore custom prototypes for turning repetitive spreadsheet steps into repeatable, inspectable workflows.

Simple internal tools

Plan lightweight member records, usage logs, or scheduling tools around your actual business rules, subject to scope and security review.

NEW TOOL / KOREAN INTERFACE

Merge multiple CSV files.

Try a browser-only CSV/TSV merge and exact-row deduplication demo. The tool currently has a Korean interface.
